Double-wedge prism scanners are typically used for one-dimensional (1D) scanning in imaging systems. This type of scanner operates on the principle of two identical wedge prisms counter-rotating around the optical axis with identical angular velocity in order to move the image formed by the optical ...

This study involved patients from the North-East Indian population, where the numbers of reported cases are increasing rapidly and alarmingly. Oxidative stress, based on 8-OH-dG levels, was found to be significantly higher in gallbladder anomalies (cholelithiasis [CL] and cholecystitis [CS]) and GBC at the plasma and DNA level, and was associated with GBC severity. The expressions of key BER pathway genes were downregulated in gallbladder anomalies and GBC compared to controls, and in GBC compared to both non-neoplastic controls and gallbladder anomalies. Expression of XRCC1 and hOGG1 was significantly associated with both...

Patients with other toxicities who had undergone similar imag...

Publication date: Available online 23 May 2019Source: PolymerAuthor(s): René Androsch, Rui Zhang, Christoph SchickAbstractThe kinetics of melt-recrystallization and the stability of crystal self-nuclei of poly (l-lactic acid) initially containing disordered α′-crystals with a melting temperature of around 150 °C has been analyzed using specifically designed fast scanning chip calorimetry experiments (FSC). In general, the rate of recrystallization of the melt after complete melting of α′-crystals decreases with increasing melt-temperature mainly due to the lowering of the self-nuclei co...
